When the voltage reaches 4.8 volts or less, the screen will flash, indicating

Antenna fades—represents the loss of a bit of information on that specific
antenna. Typically, it's normal to have as many as 50 to 100 antenna fades
during a flight. If any single antenna experiences over 500 fades in a single
flight, the antenna should be repositioned in the aircraft to optimize the RF link.
Frame loss—represents simultaneous antenna fades on all attached
receivers. If the RF link is performing optimally, frame losses per flight should
be less than 20. A hold occurs when 45 consecutive frame losses occur.
This takes about one second. If a hold occurs during a flight, it's important to
evaluate the system, move the antennas to different locations and/or check to
ensure the transmitter and receivers are all working correctly.
A servo extension can be used to allow the Flight Log to be plugged in more
conveniently. On some models, the Flight Log can be plugged in, attached and
left on the model using double-sided tape. Mounting the Flight Log conveniently
to the side frame is common with helicopters.
ModelMatch
™
Some Spektrum and JR transmitters have ModelMatch
prevents the possibility of operating a model using the wrong model memory,
potentially preventing a crash. With ModelMatch, each model memory has
its own unique code (GUID) and, during the binding process, the code is
programmed into the receiver. Later, when the system is turned on, the
receiver will only connect to the transmitter if the corresponding model
memory is programmed onscreen.
If at any time you turn on the system and it fails to connect, check to be sure
the correct model memory is selected in the transmitter. Please note that the
Spektrum Aircraft Modules do not have ModelMatch technology.
Frequently Asked Questions on Spektrum 2.4GHz
1. Q: After I've bound the receiver to my transmitter, which do I turn
on first when I want to fly?
A: Either one. Every DSM
Identifier) code imbedded in its signal. When you bind a DSM receiver
to your transmitter, this GUID code is stored in the receiver. If you turn
the receiver on before the transmitter, you don't have to worry about it
responding to another transmitter. The receiver will go into failsafe mode
while it waits for a signal from the transmitter with the same GUID code
it has stored. See the Receiver Power Only section for more information.
If a DSM transmitter is turned on first you can expect it to connect within
6 seconds of powering on the receiver.
